8-4 MEASURING INSULATION RESISTANCE

Use a “Dr. Robin” generator tester in megger tester mode or use a megger tester to check the insula- tion resistance. Connect a megger tester to one of receptacle output terminals and the ground ter- minal, then measure the insulation resistance. An insulation resistance of 1 megohm or more is nor- mal. (The original insulation resistance at the time of shipment from the factory is 10 megohm or more.) If it is less than 1 megohm, disassemble the generator and measure the insulation resis- tance of the stator, rotor and control panel indi- vidually.

NOTE : Turn on the no-fuse breaker before mea- surement.

*STATOR

(1)Measure the insulation resistance between BLUE lead and the core.

(2)Measure the insulation resistance between WHITE lead and the core.

(3)Measure the insulation resistance between YELLOW lead and the core.

(4)Measure the insulation resistance between BROWN lead and the core.

*ROTOR

Measure the insulation across one of the soldered terminals of the rotor and the core.
